create-pull-request: add option -a to auto push

Before this patch, we need two steps to create PULL:
* Step 1, create branch:
  $ git push <contrib> <local_branch>:<remote_branch>
* Step 2, create PULL:
  $ create-pull-request -u <contrib> -l <local_branch> -b <remote_branch> -r <local_branch>~<n>

We can see that the args used in step 1 are in step 2, so we can use
"create-pull-request -a" or set CPR_CONTRIB_AUTO_PUSH in to create the
branch to simplify the steps.
